Question 8. For each of following organic acids fill in the table: acid Draw the conjugated base Mark by X the strongest acid Estimate eka BEBE

Answer 1

( Conjugate base by removing of an acid is obtained the Ho from the acid. Conjugate base We remove from that position of the structure . so that the carbanion formed is stable. Here the negative charge is in conjugation with either of the two earbonyl groups which makes it stable. I

ugate base. ی ی ی ی ی ی ی Conjugate base least b lo This will form the l o stable conjugate base out of the four given Stouctures. This carbanion is being stabilized by the presence of electronegative fluorine. as well as the Sarbanion is in Congation with the two carbonyl groups present. making But due to this the negative e charge will be less available for a coniugation with the two carbonyl group, which was giving the carbation itts stability gery Conjugate base

3 The strongest acid will be the first one. since it is forming the most stable conjugate base. I (x) AAA (strongest acid Higher the acidic strength lower will be the pka. i First will have lowest pka. Il lowest pka. Pighest pka.
